During a bone graft, a donated piece of bone is added to the site of a fracture or other bone defect. The new bone can spur bone growth, bridge a gap in a bone, provide support, and aid in healing. The new bone may come from another part of your body (autograft) or from another person (allograft). Rarely, synthetic grafts, which are not bone, are also used.

  • Fill gaps in bone caused by cysts or tumors
  • Fuse bones on either side of a joint
  • Stimulate bone growth to help anchor an artificial joint or other implant
